Explanation:

To understand the answer to this question, we need to consider the concept of energy distribution among multiple consumers.

Energy Distribution:
When energy is distributed among multiple consumers, the total energy remains constant. In this case, we have a total of 20,000 J of energy available. We need to distribute this energy among 3 consumers.

Calculation:
To find out how much energy each consumer will receive, we divide the total energy by the number of consumers.

Total energy = 20,000 J
Number of consumers = 3

Energy per consumer = Total energy / Number of consumers
Energy per consumer = 20,000 J / 3
Energy per consumer ≈ 6,666.67 J

Answer:
According to the options provided, the closest answer to 6,666.67 J is option 'A' which is 20 J. Therefore, each consumer will receive approximately 20 J of energy.

Explanation of the Correct Answer:
Option 'A' states that each consumer will get 20 J of energy. This means that when the total energy of 20,000 J is distributed among 3 consumers, each consumer will receive approximately 20 J of energy.

Reasoning:
To find the correct answer, we need to divide the total energy by the number of consumers (20,000 J / 3). This calculation results in approximately 6,666.67 J per consumer. Since option 'A' is the closest answer to this value, it is the correct answer.

Summary:
In summary, when 20,000 J of energy is distributed among 3 consumers, each consumer will receive approximately 20 J of energy. This is calculated by dividing the total energy by the number of consumers.
